There is a lot you can mine from the King County Assessor’s database on parcels, buildings, land values, the quality of some housing, and whether or not there are views of Mt. Rainier. I’ve been working on a map of King County based on the year buildings were initially built. The map includes only residential structures – typically single-family homes, apartment complexes, and condos. It represents the places we live and when they were built.
Darker red areas indicate older housing. Blue areas indicate more recent housing. The lighter colored areas really represent mid-century housing. The map reveals some interesting patterns, some more surprising than others. Let’s take a look.
University District and Surrounding Areas:
The island has more of a mix – I was surprised by how much appears to be more recent construction, relative to other areas of the county.
Capitol Hill, Central District, Montlake, Eastlake, Etc.:
This collection of residential parcels in Georgetown really sticks out – surrounded by industry and an airport.
Here’s most of Seattle. The colors blend together, which adds a interesting brick-like look. When viewing the whole city, the map fairly effectively shows Seattle’s historical development patterns. To the east, you can see the development of Bellevue, Kirkland, Mercer Island, and Newcastle, which has come much more recently.
More to come on this front, but wanted to get this new endeavor, nw mapt, started.
